DISINFECTING DEVICE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed M c 6, 1905. Serial No. 248,492.

To all whom it may concern:

- Be it known that LLA'wRnNon LUND, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Disinfecting Devices, ofwhich the following is a specification.

The object of my invention is to provide means for discharging a disinfectant into a water-closet tank, to the end that the bowl will be thoroughly disinfected with each discharge of the tank.

A further object is to provide a disinfecting device having a feed that will be positive and reliable in its action.

The invention consists generally in providing a disinfecting device actuated by the movement of the tank-lever to discharge a quantity of disinfecting material into the water in the tank.

Further, the invention consists in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a sectional view of a disinfecting device embodying my invention, illustrated as secured to the top of a water-closet tank. Fig. 2 is an end view of the same. Fig. 3 is a transverse sectional view through the receptacle for the disinfecting material. Fig. 1 is a partial longitudinal sectional view showing a modified construction of the feed device.

In the drawings, 2 represents a portion of the upper wall of a water-closet tank provided with the usual operating valve-lever 3 and pull-chain 4. v

5 isa bracket secured on the top of the tank, and 6 is a clamp having an arm 7, provided with a longitudinal slot 8, that is adjustably secured to said bracket byabolt9and thumbnut 10 to allow the said clamp to be adjusted toward or from the pivot of the lever 3 to properly adjust the feed-operating mechanism to the throw of the lever. The ends of the clamp 6 are connected by a bolt 11, and a can 12, preferably of sheet metal and circular in cross-section, is embraced by said clamp, and thereby secured upon the bracketoabove the open top of the water-tank. A slide-cover 13 is provided in the top of the can, through which the material may be inserted or the interior inspected at any time. One end 14 of can, and at predetermined intervals the disthe can on the under side, and a sleeve 19 is loosely mounted on said can between the cover 14, and shoulders 20 in the can-walls, and said sleeveis provided with a series of holes 21, that are adapted to coincide with the dischargehole 18 as the sleeve revolves. A shaft 22 is centrally mounted in the ends of said can and provided with an arm 23, that engages a pin 24 on said sleeve, and when the shaft is revolved the arm will push the sleeve around the can and successively open andclose the dischargeppening and allow the escape of the disinfecting material. Aspiral 25 is provided on the shaft 22 to feed the disinfecting material to the discharge-opening and insure the pressure at that point of a quantity of the material in the can.

It is desirable that the feed device he operated each time the closet-bowl is flushed. I

therefore provide a ratchet-wheel 26 on the shaft 22 and a loosely-mounted lever 27 on said shaft, having a dog 28 to engage the teeth of the ratchet 26 and connected by a link 29 with the tank-lever 3. Each time the tank-lever is depressed the ratchet and shaft will be revolved one step and the disinfecting material fed toward the discharge end of the charge-hole in the can will be exposed and a quantity of the disinfectant allowed to drop down into the water in the tank.

In Fig. 41 I have shown a slight modification, which consists in omitting the revolving sleeve and providing merely the dischargeopening in the can, which is exposed at all times and through which the material is fed into the tank with every movement of the shaft and spiral.

I do not wish in this application to confine myself to the specific means employed for supporting the disinfecting device on the tank or operating the feed, as the same is capable of various modifications without departing from the spirit of my invention.

I claim as my invention- 1. The combination, with a water-closet tank and its valve-lever,of a receptacle mounted on said tank and having a discharge-opening. a positive feed provided in said receptacle, and mechanism operated by the movement of said lever for actuating said feed.

2. The combination, with a water-closet tank and its valve-lever, of a receptacle adapted to contain adisinfecting material and having a discharge-opening, a feed device provided in said receptacle, and mechanism controlled by the movement of said valve-lever for. operating said feed device.

3. The combination, with a water-closet tank and its valve-lever, of a receptacle adapted to contain a disinfecting material and having a discharge-opening, a spiral-feed device operating in said receptacle, and mechanism controlled by the movement of the valve-lever for operating said spiral feed.

4. The combination, with a water closet tank and its valve-lever, of a receptacle adjustably supported to allow it to be moved toward or from the valve-lever pivot and said receptacle having a discharge-opening, a feed device operating therein, and operative con-' nections provided between said feed device and said lever.

5. The combination, with a water-closet .thereon, a clamp adjustably mounted on said bracket, a can circular in cross-section supported by said clamp'and having a dischargehole at one end over said tank, a spiral-feed device operating in said receptacle, and a ratchet mechanism connecting said spiral-feed device and said valve-lever.

In witness whereof I have hereunto set my hand this 27th day of February, 1905.
